Ideas for Decorating New Rental?

Q: We are about to move from a charming pre-war apartment with red brick and 11-foot ceilings to a no-personality box, but significantly larger one. I am going insane trying to figure out how to make it look more personal, cozy and unique. I have three questions about that new apartment:

1) The walls in the tiny bathroom are covered with tile in some absolutely horrendous pinkish-brownish-yellowish color. I doubt the landlord will allow me to repaint them and I don't have the budget to re-tile a rented apartment's bathroom. Any ideas on how to cover or makeover the wall tiles in the bathroom? Waterproof stickers? Waterproof temporary wallpaper?

2) The window frames in the apartment are painted black. Any tricks on how to make them look like wooden frames or something else without repainting them?

3) Do you know of any table which could fit a family of 4 and fit into this tiny kitchen? Any makeover ideas for the kitchen are also welcome.
